CHURN.

SPECIFICATION forming part of 1 Letters Patent No. 481,542, dated August30, 1892.

Application filed October 1, 1891. Serial No. 407,381- (No model.)

To all whom it may concern.-

Be it known that I, GEORGE S. AGEE, of Willow Springs,in the county ofHowell and State of Missouri, have invented a new and useful Improvementin Ohurns, of which the followingis a full, clear, and exactdescription.

This invention consists in a churn of novel construction, including aswingingtreadle for operation by the foot to actuate the dasher, alsoincluding a specially-constructed dasher and other constructions andcombinations of parts, substantially as hereinafter described, and moreparticularly pointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar letters of reference indicatecorresponding parts in all the figures.

Figure 1 represents a view in perspective of a churn embodyingmyQinvention; Fig. 2, a vertical section, in direction of its Width, ofthe lower portion of the swinging frame or treadle used to actuate thedasher through the intervention of a longitudinally-arranged arm orlever; Fig. 3, a broken side view of the lower portion of the dasher,showing certain of its paddles or agitators in different positions Fig.4, a transverse section of the dasherstaff, taken above the paddles,which are also shown in part; Fig. 5, a vertical section, andFig. 6 aplan view,of the one-half of a clamp used to hold the dasher-staff andof a link which connects the clamp with the arm or lever worked by thetreadle to actuate the dasher.

A indicates a stand or base having parallel uprights B B at its one end,provided with open bearings 11 b on top for reception of the trunnionson the ends of a rocking bar or fulcrum-pieoe C. This fulcrum bar orpiece C is mounted on and made fast to the upper ends of a swingingframe D, composed of opposite uprights carrying at their bottoms apivoted footpiece E, all arranged to work within or between the uprightsBB and forming, in connection with the f ulcru m-piece O, a horizontallyor backward-and-foiwvard swinging treadle for operation by the foot toactuate the dasher through aforwardly-proj ectiu g arm or lever G. Thisarm or lever Ghas pivoted to it at its forward end, as at d, a link I-I,

ted lines in Fig.

which in its turn is pivoted at its lower end, as at e, to the one-halfof a divided clamp I 1, adjustable by a thumb-screw f and adapted, whentightened up, to hold the staff J of the dasher of the churn. backwardand forward swinging treadle and its forwardly projecting arm or leverthe dasher has its usual up-and-down motion given to it by the mereswinging movement of the foot, the pivoted link H swinging or movinglaterally to preserve the perpendicularity of the dasher.

The dasher, which works within the upright churn, tub, or can K, ispreferably constructed as follows: Attached to the dasher-staff J Bymeans of the.

near its lower end,as by pivots g, are a series (here supposed to befour) of paddles or agitators J, arranged around or on opposite sides ofthe dasher-staff and restricted, by the slots in the staff in whichtheir inner ends are jointed or pivoted, from moving up beyond ahorizontal position or thereabout, but free to close or drop into apartially-closed position against the sides of the staff, as shown bydot- As the. dasher-staff is raised by the swinging of the treadle thepaddles J fall, drop, or close, thus admitting of a free passage for thecream during the upstroke of the dasher; but when the motion of thedasher is reversedthat is, moved downward by the continued swingingmotion of the foot as applied to the treadlesaid paddles instantly openor spread outward by the resistance they encounter with the cream togive the necessary agitation to the cream in the tub K. The opening andclosing paddles J are made hollow or with cavities tin theirlowersurfaces, so that when the dasher moves downward they will, bymeans of these cells i, carrya quantity of air down with them into thecream and so facilitate the gathering of the butter. A churn thusconstructed works exceedingly light, and as the operator only requiresto swing his foot backward and forward to work the dasher he is atliberty to do other light work at the same time. The tub, can, or vesselK has an inwardly-overlapping partial or centrally open cover M appliedto and around its upper edge. This cover or guard, which may be made ofrubber or of metal constructed to spring over the tub or can, preventsthe cream from being thrown up and out of the can by the working of thedasher.

If desired, the operating portions of the churn may be duplicatedwithout changing the invention. Thus there may be two swinging treadlesoperating two levers similar to the one G for working two dashersin thesame churn, side by side. If desired, also, a screw or any otherordinary connection may be used instead of the clamp I I forattachingthe link H to the dasher-staff. The cover or guard M isdesigned to be used over the ordinary churn-lid. (Not shown in thedrawings.)

Having thus described my invention, what I claimas new, and desire tosecure by Letters Patent, is

1. In a churn, the combination, with asuppcrt, of an angular rockingframe pivoted at its angle to said support, a foot-treadle at the lowerend of the vertical member of said rockparallel uprights, of an angularframe pivoted at its angle between said supports, a dashershaft clampsuspended by a link H from the outer end of the horizontal member ofsaid frame, the vertical member of the rockingframe being formed ofparallel bars provided with a treadle or foot-piece between their lowerends, substantially as set forth.

3. A churn comprising the base A, vertical uprights B B, the angularrocking frame pivoted at its angle in the upper ends of said uprights,with its horizontal arm G overhanging the base and provided with adepending pivoted link carrying at its lower end the elamping-jawsI I,the vertical member of the rocking frame being formed of two parallelbars having a foot-piece pivoted between their lower ends, and achurn-body having a dasher provided with a shaft held between saidclamping-jaws, substantially as set forth.
